For the majority of chill songs, especially those made here in Auxy, I tend to notice a lot of soft snares (reduced lowpass) and multiple percussion sounds, such as claps, snaps, and sometimes toms. It’s adds a nice foundation for the track, and especially with Auxy’s new drum library, you really want to hear some nice and new drums here and there.
Your song is really nice, but I’m not entirely sure all of it fits under the chill genre. Well, a lot of it is, but it’s missing some parts. I love the melodic percussion, but in my opinion it does need actually snare clap percussion.
When I’m making ambient music, I typically strive to make music people would actually want to put their headphones on and relax to, maybe even fall asleep to. For many genres, that would be offensive, and I agree. But for chill songs, you want to let the soft sounds get to you. That being said, the bass in Passing the Red Giant seems to get stronger at many parts and doesn’t fit with the rest of the instruments. I think it’s… a boom bass? That’s the thing, the word ‘boom’ definitely doesn’t fit with ambient music.
You certainly need bass in chill songs to really make the track sound complete and to get that lower octave in there. But strong basses fit better for EDM sort of tracks.
